I NEED help converting my introductory paragraph into my conclusion!!!?

In the Great Gatsby, Francis S. Fitzgerald includes many historical figures and events that contribute a great significance and detail throughout the story. Francis sets the novel during the 1920s, which was also known as the “Jazz Age”, when prohibition was in effect. He also uses Meyer Wolfsheim as a clear allusion to Arnold Rothstein due to their close similarities in characteristics and lifestyle. Ultimately, Fitzgerald could not have chosen a better time or cast of characters to represent the riotous lifestyle of the Roaring Twenties.
